The HRVOC GC system is designed for analytes recently targeted by the Texas Commission on Environmental
Quality (TCEQ). Ethylene, propylene, 1,3-butadiene and butenes have been found to contribute to high ozone observed
in the Houston area. It is believed that substantial emission reductions of these four compounds are likely to have a
high impact on the rapid ozone formation and transient high ozone in the area. To that end, the TCEQ requires that
facilities in the Houston/Galveston area with a vent gas sream, flare or cooling tower heat exchange system that
emits HRVOCs (or has the potential to emit HRVOCs) continuously monitor their systems for composition and flow.
